On the substantive point of the trademark infringement, I had the impression that if you don't defend a trademark then you lose it. Iceland have been displaying their name in huge illuminated signs all over the UK for decades so how the Country can now come along and act shocked I can't imagine.

It's not the defense itself that's the important part. If you don't defend a trademark and it's used more and more to refer to things other than those you're selling, you risk the trademark becoming a generic term for... well, refrigerated food in this case, but w/e. The law cares only minimally about the amount of vigor with which you've defended the trademark against genericity; the important thing is whether it's still a trademarkable word or not. In this case, "Iceland" isn't used by anyone as a generic term, so the genericity stuff doesn't come into play.

What might come into play is "laches", the legal doctrine that if Iceland-the-country has let Iceland-the-store spend decades opening stores and advertising and building brand awareness, it's no longer equitable for a judge to simply take the trademark away from Iceland-the-store. IANAL and I certainly ANA international trademark L, though, so it's possible that laches cannot bar this claim.

The booklet had a spiral which took some time to figure out. Basically, 2 pieces in the middle, and 1 on each side of it, which makes it look really cool, and more importantly, supports the turned pieces. They do a slow turn though.

Rotating with respect to itself. Every particle in that space station (assuming it's rotating) is under tension, experiencing a net force and hence a net acceleration. Let a bit go, and it'll fly off in a straight line. (At that point, the particle could argue that it's at rest, and the space station is both rotating and moving linearly, because the particle *would* be in an inertial reference frame.) You don't need a reference frame to measure force, just velocity.

As for whether observing a rotating object implies that "something" must have accelerated it in the past, that's a question for the philosophers.

Hmm? Sure. A rotating space station is a non-inertial reference frame, in the sense that objects in it are undergoing acceleration (caused by the tensile force holding their particles together). So you can just measure the apparent centrifugal force at a particular radius, do a little math, and find out the angular velocity of each ring. Or you could just jump off the stations. As you floated away into the void, you'd see whichever ones were rotating, rotating. (Better bring a radio, so you can tell the rest of us. Or a rope, I suppose.)

In an attempt to test whether the higher numbers of cardiovascular deaths were simply a statistical blip or a genuine sign of the effect of traveling into deep space, the scientists exposed mice to the same type of radiation that the astronauts would have experienced. After six months, which is the equivalent of 20 human years, the mice showed damage to arteries that is known to lead to the development of cardiovascular disease in humans.

Well, no. The scientists slammed the mice with ~6-12 months' worth of radiation in ten minutes. Yeah, they probably had artery damage. Stuff like that happens when you stick a mouse in the microwave.

One generally uses a long, complex password for their password vault (which is fine, since you only have to remember the one password). This, combined with PBKDF2 backed by SHA-256 iterations, means that it's not realistically possible to brute-force the vault before the sun goes out.

The problem again is LastPass. Nobody knows if their security practices are any good, and the attack surface is huge.

Well, their online security practices are relatively unknown, but they're also kind of beside the point. Yes, LastPass won't hand out someone's vault without some sort of authentication, but that's just fences around brick walls. The real means of security is in the client, which is the only part capable of decrypting the vault (decryption keys never being uploaded). The client source code is available and has been audited, so you can feel pretty good about that, short of the Ken Thompson hack or the possibility of the local computer itself being hacked (which, of course, would affect any password manager).
